Hydraulic motor is a commonly used hydraulic transmission device. It drives the output shaft through the flow of liquid to the inside of the motor for rotating or linear motion. So what is the power of hydraulic motor? Let's introduce it in detail below.
The power of the hydraulic motor is mainly determined by two factors: the working pressure of the hydraulic system and the displacement of the hydraulic motor. Among them, the higher the working pressure of the hydraulic system, the greater the power output by the hydraulic motor. The displacement of hydraulic motors refers to the volume occupied by the liquid flow of the hydraulic flow through the motor. The amount of liquid flowing through the unit time is also an important factor affecting the power of the hydraulic motor. The larger the displacement, the higher the power that the hydraulic motor can output.
For the power calculation of hydraulic motors, the following formula is usually used:
P = q × p
Among them, P represents the power of the hydraulic motor, the unit is a kilowatt (KW); Q represents the flow of the liquid flow, and the unit is litter/minute (L/min); P represents the pressure of the hydraulic system, and the unit is Maza (MPA).
For example, if the displacement of the hydraulic motor is 50 L/min, the operating pressure of the hydraulic system is 20 mPa, then the power of the hydraulic motor is:
P = 50 × 20 /600 = 1.67 kW
According to the above calculation method, the power of the hydraulic motor is directly related to the working pressure of the hydraulic system and the displacement of the hydraulic motor. For the same type of hydraulic motor, the greater the displacement of the hydraulic motor, the higher the output power of the hydraulic motor, and the higher the output power. At the same time, the working pressure of the hydraulic system can also increase the power of the hydraulic motor. However, when the actual use of hydraulic motors, the working pressure of the hydraulic system should be reasonably selected according to the specific application conditions and the displacement of the hydraulic motor to achieve the effect of use.
In general, the power of the hydraulic motor is determined by the working pressure of the hydraulic system and the displacement of the hydraulic motor. In actual use, it is necessary to adjust the working pressure of the hydraulic system and the displacement of the hydraulic motor according to the specific application scenarios and the need to adjust the hydraulic system to achieve the effect of use.
